transmission oil cooling line ports

Post by laskin » Thu Mar 14, 2019 4:14 pm

Hey all, just putting my 450b back together after a major tear down and I can't remember where my trany cooling lines go. my question is which port coming from the trany is the supply to the cooler and which is the return from the cooler? Thanks for any replies.

It appears there were two different routings on 450Bs, based on early (S/N 142199 and before) or late (S/N 142200 and after). These are shown in the Technical Manual (TM1033). If you don't have a copy there is a Free (something unusual) downloadable copy at https://archive.org/details/John_Deere_Company . The parts catalog (PC 1170) shows different tubes related to the serial number break. Checking this info out may give you the info you need based on your serial number. If you don't have a link to the on-line parts catalog site here is one. https://jdparts.deere.com/servlet/com.d ... anguage=19 . HTH

I'm not sure if it would matter which way you install the lines. Doesn't the fluid just flow thru the cooler and return to tranny?

Sounds like he is not sure of the ports at the transmission. The filter is in the return line from the cooler to transmission, so I think the flow has to be the right way.

I forgot about the filter.

Thanks for the reply guys! Yeah Jim b you are right the fluid has to go through the filter housing the right way, I think I got it figured that the forward port is the supply... another thing I was wondering is about how the side frames attach to the clutch housing. When I disassembled mine things where broken and cracked hence the main reason I tore it down. I ended up changing the clutch housing because it was cracked. Anyhow from what I gather the side frames don't suck tight to the clutch housing but rather they are just located by a large spacer in the bottom hole and a smaller spacer on top? Can anyone shed some light on this? I will attach a photo as soon as I figure out how. Thanks

I have a 450B trackloader.
There is a spacer that goes between frame and clutch housing- 2 bolts on the side of frame into housing and one bolt from the bottom into the spacer.

If you still have questions on tranny oil lines- I can check mine and let you know. 14400-

450 tranny hoses

On the right side of tranny:
Front line runs on top- goes to bottom of cooler.
Then, from top of cooler hose runs to outside of filter holder.

Rear line “t’s” off case (back of t takes the steering cylinders return) and runs on bottom- runs to “t” for steering pump and on to center of filter holder.

Hope that helps
